I had the belief to beat Serena: Maya

When Serena Williams accepted an offer to play singles at Wimbledon, Maya Joint got to thinking.

The 20-year-old Joint had said there was “always a part of me that wanted to experience playing against her.”

After getting what she wished for - a first-round meeting with the tennis icon — Joint delivered on the biggest stage.

The Michigan-born Australian showed few nerves in winning the biggest match of her life - defeating Williams 6-3, 6-7 (6), 6-3 on Tuesday to spoil the 44-year-old Williams’ singles comeback at the All England Club.

“I didn’t get much sleep last night. I was up until like 2 a.m. just thinking about it,” Joint said in her on-court interview.

The 87th-ranked Joint certainly looked calm on the outside but said she had serious butterflies walking onto Centre Court alongside the GOAT of women’s tennis.

During warmups, she felt like her legs “weren’t moving.”

“I really don’t know how I got a pretty good start in the match,” Joint said. “She has such an aura, she’s just a legend and this court has so many huge names that have played on it. I’ve been dreaming about this moment since I was a little kid, so this is pretty crazy.”

Joint notched her first Wimbledon singles win and just her third Grand Slam singles victory.
